Abstract

The invention relates to a refrigerator and a roller component. The roller component comprises a roller and a rolling shaft; the roller comprises a roller main body and a roller bush which are integrally injection moulded; the roller bush completely covers the outer periphery of the roller main body; the roller bush is provided with a cylindrical outer periphery; the roller bush is made of a flexible material; one end of the rolling shaft is a fixed end and is used for external connection; the other end of the rolling shaft is a connection end and is used for supporting the roller main body and the roller main body can rotate on the connection end; and an axial limiting structure is arranged on the connection end and is used for axially limiting the roller main body. According to the roller component, the number of parts can be reduced by utilizing the integral moulding structure of the roller; the roller main body and the roller bush are integrally moulded, and no clearance is formed,so that swinging is not caused; during rotation, the roller main body supports the roller bush, and the bush is made of the flexible material, so that soft contact between the roller and an externalcomponent is realized; vibration of the roller during a moving process is absorbed, so that smoothness of rolling of the roller is improved; and noise caused by movement of the roller is lowered, andthe effect of muting and soundlessness of the roller is realized.

Description

technical field [0001] The invention relates to the technical field of packaging structures, in particular to a refrigerator and a roller assembly. Background technique [0002] Refrigerators are commonly used appliances for storing food at low temperatures. With the development of technology, refrigerators are becoming larger and larger. In a large-capacity refrigerator, it is usually divided into multiple storage areas, and some storage areas use drawers to take and place items in a pull-out manner. [0003] In the related art, the movement of the drawer in the refrigerator usually requires the cooperation of roller components. The roller components currently on the market usually use ball bearing roller components. The roller components with this structure have defects such as many parts, many processes, large gaps, easy shaking, and high noise. The manufacturing cost is high, and the processing and installation are relatively cumbersome. Contents of the invention [...
